WINDNIILL-REGULATOR.

SPECIFICATION forming part 0f Letters Patent No. 493,163, dated March 7, 1893. Application liled November 10, 1392.- Serial No. 451,540. (No model.)

T0 all whom it may concern,.-

Beit known that I, HENRY J. HAUFF, a citi- Zen of the United States, and a resident of Magnolia, Harrison county, State of Iowa, have invented certain newv and useful Improvements in Windmill-Regulators; and my preferred manner of carrying out the invention is set forth in the following full, clear, and exact description, terminating with claims particularly specifying the novelty.

This invention relates to wind mills, and more especially to the regulators therefor; and the object of the same is to construct a device wherein the operating pawls will be caused to engage the ratchet teeth on the drum suddenly when the float rises to a given point, instead of moving slowly into engagement therewith as heretofore.

A further object is to produce improvements in details to eifect the better working of the whole, prevent sticking of parts, and reduce friction to a minimum.

To this end the invention consists in a wind mill regulator constructed substantially as set forth below and as illustrated in the drawings, wherein- Figure 1 is a rear elevation of the wind mill tower, illustrating the tank in section and showing the connection between the float therein and the regulator proper. Fig. 2 is an enlarged front elevation of the regulator proper, showing the pawls disengaged from the drum so that the wheel will rotate to till the tank. Fig. 3`is a similar View, showing the pawls engaged with the drum and the latter turned so as just about to stop the motion of the wheel-the tank being nearly full. Fig. 4 is a perspective det-ail of the trigger, the arm for turning it in one direction, the spring for turning it in the opposite direction, the two pawls and their operating levers, and the rods connecting the trigger with the pawls.-

Referring to the said drawings, the letter W designates the tower of the mill supporting a wind wheel M and preferably also supporting a storage reservoir S at some distance from the ground. The wheel causes the vertical reciprocation of the pump rod P whereby water is pumped up the pipe p into the reservoir, whence it flows through pipe s into the tank T when a valve V is opened to permit: or, the reservoir S may be omitted and the pipe p connected directly with that lettered s, when the water will pass directly into the tank. The latter contains a lioat F connected by rods and levers f (or other suitable devices) with the regulator R, and from the drum of this regulator leads the regulator wire r which throws the blades of the wheel M into or out of the wind, as is common in devices of this character and needs no further explanation here.

Coming now to the present invention, the regulatorR consists of a drum 1 journaled on a shaft 2 and having a portion of its periphery struck on a slight eccentric decreasing in diameter from a to b and provided with ratchet teeth 3, while the balance of its periphery is untoothed as at 3. The regulator wire r passes around this drum oris attached to an arm 1 of the drum as shown, and leads thence to the wheel. Pivoted on the shaft 2 is a lever 4 connected by a link 5 with the pump rod P, this lever carrying the main pivoted pawl 6 capable of engaging the teeth 3. Pivoted between its ends to a support 7 is a rock lever 8, one end of which is connected by alink 9 with the main lever 4 and the other end of which carries a long pawl 10 capable of engaging the teeth 3 on the drum at a point above wherethe pawl 6 engages them.

When the pump rod is reciprocated by the rotation of the wind wheel, the levers cause their pawls to move simultaneously and oppositely, and when the p awls are engaged with the teeth the drum is turned with an increasing force as the longer teeth at a come under the tip of the long pawl 10. The shaft 2 is preferably mounted at its forward end in a bracket 11, and pivoted on a pin 12 in this bracket is an arm 13 whose lower end is pivoted to a slide 14 which is moved inward by the rise and outward by the fall of the float F-the arrangement effecting these movements being that shown or any similar construction which will produce them.

Pivoted at 16 to the bracket 11 is a trip 17 whose upper arm is turned forward as at 18 and provided with an eye 19, and whose lower arm has a cam-shaped upper edge 2O resting under a pin or stud 21 in the arm 13, and a notch 22 near its extremity.

IOO

Pivoted on the pin 12 is atrigger23 having a sharpened lower end 2l adapted to engage the notch 22 when the slide 14 is moved outward by the descent of the fioat, as seen in Fig. 2.

25 is a spring coiled on the pin 12 with one extremity passing through the eye 19 of the trip an d holding its lower arm normally raised against the stud 21, and its other extremity bearing the lowerend of thetrigger normally to the right. At the upper end of the arm 13 is a heel 29 which engages against the trigger, when the slide is moved outward, and turns said trigger against the force of the spring` 25 so as to permit its sharpened lower end 24 to be brought over the notch 22 of the trip and engaged thereby.

The main pawl 6 is of the ordinary construction except that it has a lug 30 projecting outward from its tip; but the long pawl 10 preferably has a forked tip 3l, as seen in Fig. 4, which engages the edge of the drum, and a pin or lug 30 projects outward from this pawl also near its tip.

32 and 32 are rods whose inner ends are attened and pivoted as at 33 to the upper end of the trigger 23, and whose outer ends have slotted eyes 3l and 34: loosely engaging the lugs 30 and 30 respectively. The parts are of the desired shapes, sizes, and materials, and considerable departure may be made from the exact construction shown.

'lhewind wheel being rotated by the breeze and the pump rod P reciprocated vertically, water is pumped up the pipe p into the reservoir S and may be drawn therefrom through valve V into the tank T; or the water may flow directly from pipe p to pipe s and into the tank, as in dotted l'nes Fig. l. When the tank has become sufleiently full the float F will have risen to the position shown in Fig. l and the slide 14e will have been moved inward. Such inward movement of the slide turns the arm 13 on its pivot from the position shown in Fig. 2 to that shown in Fig. 3, and as it so turns the stud 21 passes along the cam face 2O of the trip 17 until the notch 22 is disengaged from the lower end 24 of the trigger; and-the heel 29 having meauwhile moved away from the triggerthe latter is freed. lts spring 25 then causes it to turn to move its upper end to the left, and the tips of the pawls are drawn into engagement with the teeth 3, after which the continued reciproeation ot' the pump rod P will turn the drum l on its pivot 2, and the arm l will draw down on the regulator wire until the blades of the wheel M are thrown out of the wind in the usual manner and the wheel ceases to rotate. Tater being now drawn from the tank, as by stock drinkingtherefrom, the float F falls and the slide 14 is moved outward. The stud 21 passes down the cam Such movement of the trigger pushes on the rods 32 and 32 until their slotted eyes 34 and 34 engage at their inner ends against the lugs 30 and 30 and push the tips of the two pawls out of engagement with the teeth 3: then the spring which aetuates the regulator wire draws on the same to throw the blades again into the wind and cause the wheel to resume its rotation, the drum turning back to the position shown in Fig. 2.

It will be noticed that when the tank is full and the parts at rest the wheel cannot be set in motion from the ground. As the float lfalls Vand the arm 13 turns,the stud 2l passes down the cam face to first release the trip, then the heel 29 engages behind the trigger and turns the latter so that the slotted eyes 34- and 34 move over their pins 30 and 30', and finally both pawls are suddenly disengaged from the teeth 3,1.l1e drum turns upward to slackcn the regulator wire, and the wheel resumes its rotation at full speed. It it is desired at this time to clean the tank T, the handle 7" at the lower end of the regulator wire extension fr" is drawn upon and the wheel ceases to rotatewhat little water remains then in the tank being drawn off or dipped out as will be understood. When tension on this wire r is re leased, the wheel commences to rotate, and the tank is filled again. As the float rises, also, the arm 13 turns to move its heel out of the way and the stud 21 along. the cam face 2O until the trigger is suddenly released and its spring 25 turns it to draw the two pawls simultaneously and fully into engagement with the teeth-after which the continued reciprocation of the pump rod positively turns the drum until the regulator wire throws the wheel blades out of the wind. The lost motion in the eyes 34 and 34 permits each pawl as it moves upward to slide over the teeth 3, while the other pawl is moving downward and in full engagement with them.
